Thank you viktor!Cheers Ian, the scape looks great!
On the glass stuff, i do like them too, but for your 2073 this is probably too small. Has only a few stripes where it pulls in the water, so you will loose a few hundred lph from your filter power as 2073 is around 1000lph
This stuff is good for a nano with a filter size around 400-600lph above that size you will see decreasing on the flow
I was worried about that as well, however, it has a quite a large hole in the bottom of the pipe, a little like the Cal aqua inlets. Because I'm a bit sad, I loosely measured the flow...The method I used was to measure the amount of water pumped out in 10 seconds, then x6 to get output per minute, then x60 to get output per hour.
It's currently doing just over 800lph. I know George is also using one of these on his scape as wel, and flow doesn't appear to be a problem in his tank.
I was gonna get the 13mm inlet from TMC, but that really did only have about 6 slits in it. I decided against that one.
